What is the difference between the multiple listings for this company (Vulcan Energy Resources)?

Disclosure: I do not hold stock in this company but I would like to.

Here is a screenshot of what I mean.

I'm interested in investing in this company, specifically due to their extraction project in Germany, but I'm unsure of the best/correct way how to do it, as in which of these to buy into.

They all seem to represent the same company, and are clearly listed on different exchanges, but they are valued differently and they don't gain/lose value equally.

How can I understand this better?

Thanks for your help.
